apt-get upgrade wants to delete many packages

[drowsy]

I usually run "sudo apt-get update; sudo apt-get dist-upgrade" to update package on my Debian testing,
but recently apt started saying it wants to delete a whole bunch of packages:

The following packages will be REMOVED:
atril calendar-google-provider chromium chromium-browser chromium-common darkplaces doxygen-gui ffmpeg freedoom
...
icedove ... thunderbird ... mpv etc

I cannot understand why. Does anybody have an idea?
Below is the full apt output:

This is normal with all the changes going on.
apt-get upgrade for a while until the repos get all the necessary package versions.
